I have been asked to make a presentation/talk to a MUG on Genealogy and its interaction with today's computers, Mac mainly.

Having never made a Mac presentation before I wonder if there is a simple app within the Mac suite that I could use to prepare such a show.

I have used Powerpoint many years ago on a PC but now require something similar on a Mac that will be shown on a screen via a Mac Book but constructed on my iMac at home. Presumable I can save it all on my 512mb flash stick and take that and plug in.

Hoping for some ideas and inspiration.

Why not go with keynote

Ditto keynote, this article is a bit dated, but it is about Teh Steve and successful presentations:
How to Wow 'Em Like Steve Jobs

Also, just FYI, Office exists for the Mac. So you could use Powerpoint. But Keynote is both cheaper and more advanced.
